What Affects Ducted Heating Cost?
- Floor area to heat: This calculator prices ducted heating by square metre, so larger homes cost more to heat and require a bigger system. At the listed rates, the total rises directly with the number of square metres entered.
- System tier and brand: Brand and product tier have a big impact on ducted heating unit replacement cost and new installs. Budget systems are priced at AUD 28/m², mid-range systems at AUD 36/m², and premium systems at AUD 46/m².
- Single or double storey home: Double-storey homes use a 1.3 multiplier on the base per m² price, which increases the overall installation cost. Single-storey homes use a 1.0 multiplier, making them cheaper for the same floor area.
- Minimum job charge: If the calculated total comes in below AUD 3,500, the minimum job charge applies instead. This means smaller jobs may not reduce in price as much as the per m² rate suggests.
Ducted Heating Cost - Frequently Asked Questions
Using the default 180 m² example, a single-storey budget system comes to AUD 5,040, a mid-range system to AUD 6,480, and a premium system to AUD 8,280. For a double-storey home of the same size, those figures increase to AUD 6,552, AUD 8,424, and AUD 10,764. The displayed estimate range is then shown at plus or minus 18% around those midpoints.
The calculator uses fixed per m² rates: AUD 28/m² for budget, AUD 36/m² for mid-range, and AUD 46/m² for premium systems. If your home is double storey, the total is multiplied by 1.3. A minimum charge of AUD 3,500 applies where the calculated amount is lower.
The biggest cost drivers are the floor area to heat, the system tier you choose, and whether the home is single or double storey. For example, a 180 m² premium single-storey system is AUD 8,280, while the same premium system in a double-storey home is AUD 10,764. That difference comes entirely from the 1.3 storey multiplier.
If your replacement is priced through this calculator, the same per m² rates apply based on home size and tier. For a typical 180 m² single-storey home, replacement pricing would sit around AUD 5,040 for budget, AUD 6,480 for mid-range, or AUD 8,280 for premium, before the displayed ±18% range is applied. Smaller replacement jobs are still subject to the AUD 3,500 minimum charge.
This page’s calculator prices ducted heating by system tier, floor area and storeys rather than by fuel type. The available rates are AUD 28/m², AUD 36/m² and AUD 46/m², with a 1.3 multiplier for double-storey homes. If you are comparing gas ducted heating cost or electric ducted heating cost, the estimate here should be treated as a guide based on the selected tier.
The displayed range uses ±18% around the midpoint calculation. For example, a 180 m² mid-range single-storey system has a midpoint of AUD 6,480, giving an estimate range of about AUD 5,314 to AUD 7,646. A 180 m² premium double-storey system has a midpoint of AUD 10,764, which displays at about AUD 8,826 to AUD 12,702.
